Abstract:
Objective To analyze MRI manifestations of huge tumors in ovary and adnexal,to improve qualitative diagnosis and differential diagnosis ability.Methods Thirty-one female patients with huge tumor in pelvic cavity confirmed by surgical pathology underwent preoperative MRI plain scan,DWI and enhancement scan.MRI features were retrospective analysis and compared with pathological results.MRI manifestations included the tumor size,signal intensity,ADC value of the cystic component,ADC value of the solid component and enhanced index.Then,statistical analysis was carried out.Results The mean size of the benign ovary and adnexal tumors was (103.04±32.75)mm,and that of the malignant was (139.29 ±49.20)mm.There was no statistical difference between the two groups (P＞0.05).The number of cystic lesions in the benign group was significantly higher than in the malignant group,while the number of the cystic-solid and solid lesions in the benign groups were obviously lower than in the malignant group.The signal intensity of the lesions was statistically different between the two groups (P＜0.05).The enhanced index in the malignant group (53.15±13.78)was significantly higher than in the benign group (3 5.3 9 ±8.1 2)(P＜0.05).Moreover,the AUC was 0.8 6 1 ,indicating that the diagnostic effect was good.There were no statistical differences in the tumor size,ADC value of the solid component and the cystic component (P＞0.05).Conclusion Benign ovary and adnexal tumors are mostly cystic,while malignance are mostly solid-cystic and solid.Enhanced index is helpful for identifying benign and malignant ovary and adnexal tumors.ADC value of cystic and solid component are not useful to identifying benign and malignant tumors.MRI is powerful in diagnosing huge tumor in female genital system and help to qualitative diagnosis.
